To all whom it may concern.'

-Be rit known that I, Emsa'. Bannon, a citizen of France, residing at Brussels, Belgium, have invented certain new .and useful `'Improvements in Telephonie and Radiotelephonic Messages or Auditions b Means of Fluid Resistance, of which the ollowing is -a specication.

, The object of the present invention is a Amethod for improving the messages sent by telephone or wirelesstele hone,'andthe auf ditions (concerts or the e) given by the same means, in order to obtain, on one part, Ya refinement or a vsort of filteringl of the received sounds by eliminating any parasite noises and, on the other part tol permit the audition by-such a large number of listeners as may be desired, 'without the sound perceived by eve one of them being weakened. This metholdY consists essentially in switchin the telephonie circuit, or inthe'wire" less reception circuit, one or several liquid resistances of any suitable form and dimen-A sions.

,This method will ermit to have'the sanie-v audition listened to` ya very large number of persons, by connectin any desired number of receivers in para el on one of the liquid resistances of the circuit. The ,invention moreovercontem lates an ap liance for the realization of saidmethod. order that the following description. may be more easily understood, samewill refer to the appended' drawings which showV a practical embodiment of the invention, `given as example. y Fi 1 illustrates an installation according, to this invention for a tele honic audition. Fig. 2 is a modification o same.

appliance for receiving wire- VFig. 'Z illustratesan installation used for permitting, a large number of persons simul' taneously listening to4 a wireless audition,

. by connectingan intermediate telephonie Figs; 3-4-5-6 illustrate several forms of4 the same circuit, asseeii in Fig. 2. g

i with the other wire 9 are connected any desired number of conductor-wires `4, 4', 4

etc. each being coupled with a receiver such as 5, 5', 5" etc.

This circuit of every receiver shall be passed the naked end of the corresponding wire. Said insulating `parts 7 are intended to avoid any prejudicial contact between the ends of the several wires 6, 6', 6" or between said wires andthe other points of the cirV cuit.

The circuit Aof every receiver shall be closed when required, by dipping into the liquid, the-corresponding part 7 Same can beof the desired density either to iioat on, or

lto sink into the liquid, as re uired.

Now, a given number o persons being placed around container 3, every one can -bear oneof the receivers to her ears, but shall hear nothing. However, by dipping into the liquid the part 7 corres onding to her rev ceiver, each' of them w 1 close the circuit and hear clearly the sounds emitted before the distant micro hone.

It will thereby e possible to have a numsii'ed, to

1, can be resorted` to. The cup-shaped or other suitable container 3, is located on a table, or other suit-able article of furniture 8, the foot oi which is hollowed for the passne of said wires, such as 1passes throu h the table and ends in the container 3.v e

other wire mayl be coiled around the table provided with A receivers, as shown in the drawing.

When required, several similar devices 'can be shunted on the saine circuit; Also, several ones 'can be connected in series with one an `The operation is the same in every- The number of containers 3 can thusbe increased at-w`i11`, and so large a number of ooks 10v forha'nging the idleV ics the auditions to persons nonconversant with its working.

In fact, for ,every listener, it seems as if the perceived sounds were emittedin the liquid enclosed in container 3. Said li uid has thus appearingly acquired the peculiarity of singing, speaking etc. which enticed the inventor to give this method and appli ance the name of singing-water.

Of course, any conducting-liquid maybe used. The intensity o'f the perceived sounds increases with the conducting-power of the liquid. Goods results can be obtained by the use of plain water;v distillated water -weakens the sounds, whilst same will be stronger when someacid, basic, or salt electrolyte is dissolved in the water.

The grouping of the several receivers connected to the liquid resistances, permits of forming a whole givin the same resultsas the loud talker wit out having'its disadvantages, tlie chief advantage bein that the `useful sounds alone are strengt ened, but not the extraneous sound, as occurs with the loud talkersl One of the receivers can be at. Xwill, replaced by a loud talker connected with the liquid resistance, the sounds thus emitted by said loud talker being improved by the refinement or iltering through the liquid resistance.

The method according to this invention, can also beresorted to for receiving wireless It will be suliicient to switch into thecircuit of the receiver or receivers, one

or several liquid resistances of suitable shape. The same refinement and filtering of the sounds will be obtained. Figs. 3-4-5-6 illustrate an example of embodiment ofk this method. 11 is the ampliier;-12 and 13 the wires in connection with the receiver.

In one of said wires (Figs. 3 and 4) orin both, Figs. 5 and 6) are switched one or several liquid resistances, that can be made of tubes 14 enclosing a suitable conductingv liquid, or of containers 15 of any suitable shape. Y

It will alwaysxbe'possible, by adequately proportioning the volume of liqui or by suitably choosing said liquid (pure t r, distillated water or electrolytic solution) to graduate or `variate at a leisure, the quality Y of the received emissions.

The method of'this inventioncan alsobe used when it is desired to have a large numencl'osinfr one, two or more Aof the above described iquid resistances.

It is thus possible to have any large numcerts, auditions or the like, recelved by the wireless-telephonic apparatus on which the receiver is switched.

The same results are obtained as when using aloud talker, but without alteration4 of the audition or increase of the extraneous sounds, as is the case with the loud talker.

The wireless receiver l@ can be disposed on the end of a bar 18 moveable on a slide 19 and allowing any desired, adjustment of the distance between theA wireless-receiver and the microphone.

arrangements are merel given as examples and Ywithout limiting t e scope of this invention.

Claims:

1. The method 'of imprqving' the telephonic or wireless messages auditions, concerts, and the like transmitted in an electric circuit,'consistin `in introducing in series into the circuit o a receiver or receivers one or more liquid resistances. l Y

2.. In receiving telephonic wireless or like auditions by means of an electric circuit; the combination of liquid resistances connected in the circuit in series and a' number ofreceiver circuits each including a terminal for insertion into the liquid resistance to com'- plete the circuit in order to allow a large number of persons to hearthe audition simultaneously. 3. An appliance yfor telephonic audition by a large number of persons-comprising a telephonic circuit, a container adapted to enclose a conducting liquid in which one ofv the wires of the telephonic circuit 'terminates; a microphone in the circuit in front of which the sound (such as a concert) is emitted, a number of receivers each connected in a circuit with the" second wire of the telephonic circuit onone side and with the liquid resistance at the other side wheref by severalf/'f said containers can be connected 1n shunt and others 1n series 1n one and the same circult.
